Diabetic Retinopathy (DR) is a sight-threatening risk inflicting disorder diabetic patient. It occurs due to damage in the retina as a result of diabetes. Glaucoma is a disease of the retinal system that damages the optic nerve of the eye and gets worse over time. A buildup of pressure inside the eye is often associated with it, so it can damage the optic nerve that transmits images to the brain. If damage to the optic nerve caused by high eye pressure continues, glaucoma causes permanent vision loss. Early diagnosis and treatment have been shown to prevent blindness and visual loss. Compared with the manual diagnostic methods, automated retinal analysis systems help save patients’ time, cost and vision. In this context, a fundamental process for diagnosing these diseases is the precise and effective localization of the Optic Disc (OD) in retinal images. This paper offers a robust and efficient method for automatic diagnosis of OD. The method starts with removing the undesirable portions of the image, such as noise, reflections and blur. Next, the OD has been detected by means of morphological operations considering the intensity threshold feature. The proposed method is fast and robustness to detect OD even if interrupted by the visible blood vessels. This method was applied on seven data sets which are the Origa, Rim-One 3, Drishti, Messidor, Drions, Diaretdb0 and DIARETDBI, and the resulted accuracy for these data set are 98.46, 97.48, 97.03, 98.75, 97.27, 95.38, 95.45 respectively.","PeriodicalId":254581,"journal":{"name":"2020 International Conference on Computer Science and Software Engineering (CSASE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130707099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generally, the digital images tampering is very subtle in order that it is not distinguishable by the system of human vision. Most of the attackers work on exploiting and misusing this property. Therefore, for preventing illegal manipulation and unlawful access for any digital image, digital images watermarking schemes are developed to hide an imperceptible watermark into a cover image. Based on the utilized application, the significant requirements for these watermarking schemes are security, capacity, robustness, and imperceptibility. In order to satisfy most of these requirements, in this paper, an efficient digital image watermarking scheme has been proposed that relies on Hessenberg Matrix Decomposition (HMD) applied to each block produced from transforming the cover image by discrete wavelet transform (DWT). In the experiments, the obtained results show that the proposed scheme has a high performance in providing the significant requirements of watermarking; security, capacity, robustness, and imperceptibility.","PeriodicalId":254581,"journal":{"name":"2020 International Conference on Computer Science and Software Engineering (CSASE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131674696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, many interactive applications have been emerged to satisfy the requirements of both teachers and students. These applications can contribute to the ease of the data delivery processes which are essentially depending on the internet access. In this paper, new backup technique have been proposed to surpassing the issue of internet outage. The teacher quality assurance system at University of Duhok have been taken as a case study to evaluate the designed technique. The designed technique mainly focuses on overcoming the issue of internet outage while the academic staff get their students’ feedbacks. The proposed technique has been successfully designed to fulfill two main goals: first, the internet outage can recovered by adding a local backup server that can achieve parallel tasks, and this local server replace the main server when the internet connection is unavailable. Second, the backed up information in the local server will be automatically uploaded to the main server once the internet is available. The approached used in this paper minimizes three key aspects in internet-based IMSs, which are traffic, time, and IT requirements.","PeriodicalId":254581,"journal":{"name":"2020 International Conference on Computer Science and Software Engineering (CSASE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122859613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The coloured image is divided into three layers (red, green, and blue); then, the blue-layer will be selected as a cover-media for embedding. Next, the difference between two adjacent pixels of the cover-image is calculated, and the result is assigned to the second pixel. After that, a secret logo of size (256x512) will be embedded into each 1st MSB of the second pixel of the cover-image to obtain a stego-image (blue layer only). Finally, the other layers of stego-image; red and green will be encrypted using the Henon chaotic system, and they will be merged to generate the final encrypted image. The receiver has to use the extraction and recovery process to decrypt the ciphered image to obtain the original layers of the image (red, green, and blue). Also, the secret logo will be extracted from 1st MSB of the stego-image then the original cover-image will be ideally recovered via using the recovery process. The red, green, and recovered blue layer has to be combined to obtain the final original image. According to the results, the proposed approach has achieved the best embedding capacity equal to (0.5 bpp) and optimal image quality for the recovered image. The confidentiality of the stego-image and secret logo has been improved via applying Henon chaotic system. Besides, the proposed method is straightforward for implementation, and it requires a little execution time.","PeriodicalId":254581,"journal":{"name":"2020 International Conference on Computer Science and Software Engineering (CSASE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124462169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the beginning of artificial intelligent technology, multiple experiments were suggested by the researcher to develop a computer image recogniser similar to human recognition. One such application is in the speech recognition system in a noisy environment, where the visual cue representing the movement of the lips contains some essential information added to the audio signal, as well as how the person merges audio-visual stimuli to identify output words. A little, but unresolved, part of this problem is the classification of utterance using only the visual signals without the speaker’s acoustic signal being available. Taking into account a collection of frames from a recorded video for a person speaking a word; a robust image processing technique is adopted to isolate the region of the lips; then extracting correct geometric characteristics that reflect the variation of the mouth shape during the speech. The observed features are utilised by the identification stage to identify the spoken word. This paper aims to solve this problem by introducing a new segmentation technique to isolate the area of the lips together with a collection of visual shape features centred on the boundary of the extracted lips that can read the lips with significant results. Weightless neural network classifier is proposed to enhance the utterance identification with hardware implementation based on FPGA. Furthermore, A specialised laboratory is designed to collect the utterance of twenty-six English letters from thirty speakers who are adopted in this paper.","PeriodicalId":254581,"journal":{"name":"2020 International Conference on Computer Science and Software Engineering (CSASE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128030221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
